Various foodstuffs were prepared in silicone baking moulds and analyzed for siloxane migration using a previously developed and validated (1)H-NMR method. Meat loaf significantly exceeded the overall migration limit of 60 mg kg(-1) (10 mg sdm(-1)) in the first and third experiment. The highest siloxane migration found in a meat loaf after preparation in a commercial mould was 177 mg kg(-1). In ...

OBJECTIVES To screen novel small molecule compounds for inhibition of Mycoplasma bovis growth and to characterize their activity in terms of dose-dependency and ability to function in milk. METHODS Using a tetrazolium salt cytotoxicity assay, 480 natural compounds were screened to determine which of the small molecules have the potential to become therapeutic options for M. bovis prevention a...

This study aimed to determine whether the fat and protein content in dairy-fruit blends prepared using full-fat, semi-skimmed, skimmed or high-protein milk combination with freeze-dried blackberry puree influenced bioaccessibility bioavailability of polyphenols organic acids. Samples were subjected vitro digestion, after which was analysed a Caco-2 cell model. The addition resulted formation ag...

OBJECTIVE An experiment was conducted to examine the effect of dietary supplementation of dried and ground foliage of black gram (Vigna mungo L.) on feed intake and utilization, and production performance of crossbred lactating cows. METHODS Eighteen lactating crossbred (Bos taurus×Bos indicus) cows (body weight 330.93± 10.82 kg) at their second and mid lactation (milk yield 6.77±0.54 kg/d) w...

Pasture-based dairy production is used widely on family dairy farms in Southern Brazil. This study investigates conventional high input (C-HI), conventional low input (C-LI), and organic low input (O-LI) pasture-based systems and their effects on quantity and quality of the milk produced. We conducted technical site visits and interviews monthly over one year on 24 family farms (n = 8 per type)...

An improved extraction and HPLC method for the simultaneous extraction and quantitation of retinol, α-tocopherol, α-tocotrienol and β-carotene was developed to analyze commercial whole/semi-skim/skim samples of raw/pasteurized/UHT milk in transparent plastic/glass bottles and Tetra Brik containers. The sample preparation method required prior saponification at 40oC for 15 min followed by n-hexa...

The combined effects of starter culture type (SCT) and incubation final pH (IFpH) on the physicochemical and organoleptic properties of buffalo milk yogurt containing 3 g·100 g-1 milk fat were investigated throughout 20 days of storage at 4°C. The postacidification kinetics fitted to zero-order reaction for all buffalo milk yogurt samples. The reaction rate constants of the buffalo milk yogurt ...

in order to evaluate the effects of organic, biological and chemical fertilizers on yield and yield components of milk thistle (silybum marianum l.), an experiment was conducted at the research station of ferdowsi university of mashhad based on complete randomized block design with three replications and six treatments during year 2007. treatments included inoculated seeds with azotobacter, com...

Bovine milk has been shown to contain bioactive components with bone-protective properties. Earlier studies on bovine milk whey protein showed that it suppressed bone resorption in the female ovariectomised rat. A new osteotropic component was subsequently identified in the whey basic protein fraction, but bone bioactivity may also be associated with other whey fractions. In the present study, ...

In fermented products containing Bifidobacteria, factors such as organic acid concentration and b-galactosidase activity are important in the development of flavor and texture of final products. Both the process conditions and medium components have significant effects on fluctuation of such factors. The effects of whey permeate powder and yeast extract concentrations, as nitrogen sources was i...
